Current and/or former San Francisco crooner Spencer Day (his Facebook lists him as living in both San Francisco and Topanga Canyon) will appear on tonight, making this evening's show an explosion of pop-jazz tunes and handsome men. Day's appearance on the CBS late show -- which follows David Letterman -- will be a taped one. Why? Because, starting tonight, the award winning singer will appear at The Razz Room. Spencer Day's tenure at the Razz Room runs until 9/20.
